Chapter 4 Performing a Basic Startup Configuration
Configuring a Router
Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the EXEC
(also called enable mode). You must enter the privileged level of the EXEC command interpreter with
the enable command before you can use the configure command to configure a new interface or change
the existing configuration of an interface. The system prompts you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>).
At the console terminal, use the following procedure to enter the privileged level:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a
privileged-level password as follows:
Router> enable
Password:
Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
When you enter the correct password, the system displays the privileged-level system prompt (#):
Router#
Step 3 Enter the configure terminal command at the enable prompt to enter configuration mode from the
terminal.
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
At this point, you can configure the router’s host name, passwords, and other global configurations.
Note To see a list of the configuration commands available to you, enter ? at the prompt or press the Help key
while in configuration mode. For more information, refer to the Configuration Fundamentals
Configuration Guide and the Configuration Fundamentals Command Reference. See “Related
Documentation” section on page xi for more information.
Step 4 At this point, you can either:
• Save your configuration—See the “Saving the Running Configuration to NVRAM” section on
page 4-17).
• Configure the fixed interfaces on the router as follows:
– Configuring the Fast Ethernet Interfaces, page 4-9
– Configuring the T1 and E1 Interfaces, page 4-10
– Configuring the T3 Interfaces, page 4-11
– Configuring the E3 Interfaces, page 4-13
– Configuring the ATM Interfaces, page 4-15
